equivalent to a full frame 35mm of what you see in the VF
420mm = 630
600mm = 900

that's just a dumb comparison if you understand it. i'm still shooting at 420mm and 600mm. all this equivalent BS!! has done nothing but mix people up. most still think they are getting magnification instead of feild of view. the image size is the same as it would be on a 35mm or and 8'' x 10'' view camera film size if shot with the same MM of lens.

I thought you had both 2x TC and 1.4 TC with the 300mm hence the 840mm. Apparently not.

i haven't tried that yet and probably won't as the CA is so bad..
actually i got to looking at these again and the 2x, 200f is not near as bad as the 1.4x, 140f. what a surprise.. i need to shoot a comparison of the 140f and the smc A1.4x-s
here's the first shot with the 140f with no PP
